Embodiment Construction

[0024] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0025] The core processor of the system adopts the STM32f103 chip, which is connected to the wireless network through the serial port to wifi module. Adopt 802.11b wireless standard and UDP communication protocol for wireless communication. The control board receives the control signal from the local area network, and after analyzing the command, the high and low levels of the corresponding general IO port are switched to control the triode amplifier circuit. The triode amplifying circuit provides the pull-in voltage for the relay coil to make the switching action. The motor overcurrent detection control circuit is composed of current transformer, bridge rectifier circuit and operational amplifier voltage comparator. The result is connected to the IO input pin of STM32, and when the voltage of the pin is detected to be low, the shutdown program is executed.

Abstract

The invention relates to a remote wireless control circuit for an intelligent roller shutter door. The remote wireless control circuit is characterized by comprising an STM32 master chip, a wifi universal serial bus module, an infrared detection interface, a motor control circuit, a current overcurrent protection and a power supply module. A wireless wifi transceiving processing module of the STM32 master chip and a large-current relay jointly form the remote control circuit for the roller shutter door. A current transformer and a voltage comparator are adopted for motor overcurrent protection, and door opening and closing state detection is realized through an infrared detector. Wireless control and state judgment of a robot charging room door are realized by a substation monitoring background and an inspection robot. The remote wireless control circuit realizes wireless communication with a remote control terminal or the inspection robot through the 802.11b protocol, and after a processing circuit receives an instruction, a relay coil circuit formed by triodes is controlled through corresponding IO tubes, so that current direction and on-off of a direct-current motor can be controlled to further realize opening and closing control of the roller shutter door.

Description

technical field [0001] The invention belongs to the wireless communication technology, and relates to a remote wireless control circuit of an intelligent rolling door, which is used to control the wireless communication processing circuit of the inspection robot charging room door, and can execute the opening and closing instructions of the robot or the remote background while feeding back the current charging room door. open and close state. Background technique [0002] The traditional ordinary remote control door mainly completes basic operations such as opening and closing the door, and has a single function, lacking auxiliary functions such as anti-theft, over-current protection, and status feedback. It uses a fixed encoding format and cannot access the network to communicate with network devices. Contents of the invention [0003] technical problem to be solved [0004] In order to avoid the deficiencies of the existing technology, the present invention proposes a ...
